OK, brake cleaner and other solvents aren't good to breathe, and worse when
trapped or concentrated under a welding helmet. In re-reading the article in
the "Iron" magazine, the writer says he followed his "normal proceedure of
using an acetylene torch to burn off any residue". (Normally only goggles need
be used with acetylene). If he had used such a torch, why was there anything
left to create the vapors that put his health in such peril when then going on
to use the TIG welder? Som ting missin'!?
Michael's reply was right on the money, particularly about the inert gas and
it's oxygen shielding duty. (I couldn't think of this and substituted
"deoxidizer" in it's place, which wasn't correct).
So now I'll shut up...and read some of the Material Safety Data Sheets that was
sent my way.
